Abstract: A method for evaluating a measurement result of a thermal analysis. A program-controlled computer unit is used to calculate at least one probability of the agreement of the measurement result with at least one dataset previously stored in the computer unit, wherein this calculation is based on a comparison of effect data previously extracted from a measurement curve of the thermal analysis with corresponding stored effect data of the dataset. The evaluation can advantageously include, an automatic recognition and classification of measurement curves and can be carried out in particular more efficiently, more economically and more quickly than previously, with at the same time a high quality of evaluation.

Abstract: A system for measuring change in length and/or deformation force on a sample in a longitudinal direction. The system is useful in thermomechanical analysis and/or dynamic-mechanical analysis, and comprises a pushrod extending in the longitudinal direction which exerts force on the sample, and a device measuring movement of the pushrod resulting from the change in length or deformation of the sample in the longitudinal direction. The measuring device includes: a pushrod base mounted on a stationary base with a guide so as to be movable in the longitudinal direction; a controllable drive for moving the pushrod; a detector measuring the force exerted by the pushrod on the sample; and a path sensor for measuring the movement of the pushrod.

Abstract: A method for conducting a differential thermal analysis, in which a sample disposed in a temperable sample space is tempered according to an essentially linear temperature program extending from a start temperature to an end temperature, such that, from the result of a measurement of the sample temperature conducted during tempering at a number of measurement time points, a DTA signal is calculated as the difference between a measured sample temperature and a reference temperature calculated according to a temperature curve model. According to the invention, for every measurement time point, the relevant reference temperature is calculated by the following steps: (a) establish a time interval containing the relevant measurement time point; (b) calculate a non-linear adjustment function for the measured sample temperature curve in the time interval; and (c) calculate the reference temperature as a value of the adjustment function for the measurement time point.
